乳源性寡糖对仔猪肠道健康的影响及母猪乳腺合成寡糖的生化机制

摘要

Milk oligosaccharides can selectively promote Lactobacillus and Bifidobacterium rapid reproduction in the intestinal tracts of neonatal pigs. Intestinal microflora established model during the early stage of life has multiple physiological functions, such as affecting the intestinal microflora in the later stage of life, inhibiting pathogen proliferation, regulating intestinal mucosal immune development and tolerance, etc. The present paper summarized the roles of porcine milk oligosaccharides in the regarding aspects mentioned above, and additionally, the biochemical mechanisms for oligosaccharides syntheses in mammary gland were also reviewed.%乳成分中寡糖可在新生仔猪肠道中选择性地促进乳酸菌和双歧杆菌的快速繁殖.新生仔猪肠道早期菌群定植模式有许多肠道生理作用,如影响后期肠道菌群结构、抑制病原菌、调节肠道黏膜免疫发育和免疫耐受等.本文对上述方面进行综述,并同时讨论了母猪乳腺合成寡糖的生化机制.
